electro-, electr-, electri-
(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)
Electronics in our lives consists of numerous tools
Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.
2. A relay whose actuator element consists of non-conducting media separating two or more conductors which change their relative positions because of the mutual attraction or repulsion of electric charges applied to the conductors.
2. Scanning or the process of directing a radio-frequency beam successively over all points in a given region of space which involves electrostatic deflection of an electron beam.
2. A separation of finely pulverized materials by placing them in electrostatic separators.
2. A separator in which a finely pulverized mixture falls through a powerful electric field between two electrodes.
Materials with different specific inductive capacitances (capabilities of bodies, system, circuits, or devices for storing electric charges) are deflected by varying amounts and fall into different sorting chutes.
2. A type of contact electrification in which certain materials become electrically charged after they come into contact with a different material and are then separated by rubbing.
The polarity and strength of the charges which are produced are determined by the materials, surface roughness, temperature, and other characteristics.
2. A metallic enclosure or screen placed around an apparatus so it will not be affected by external electric fields.
3. A grounded metal screen, sheet, or enclosure placed around an apparatus or between two appliances to prevent electric fields from acting through the shield.
It can prevent interaction between the electric fields of adjacent parts on a chassis.
2. The placing of a grounded metal screen, sheet, or enclosure around a device or between two devices to prevent electric fields from interacting.
2. An electrostatic area which acts on an insulator.
The field generates polarization in the insulator and causes an electrical breakdown if it is raised beyond a speciic intensity.
It is designed for use in satellites, where the stored image is not damaged by Van Allen or other cosmic radiation in the upper atmosphere.
The motion of the movable electrode changes the capacitance between the electrodes and so makes the applied voltage change in proportion to the amplitude of the electrode's motion.2. A transducer which consists of a capacitor, at least one plate of which can be set into vibration.
Its operation depends on the interaction between its electric field and a change in its electrostatic capacity.
2. A speaker with a movable flat metal diaphragm and a non-movable metal electrode capable of reproducing high audio frequencies.
The diaphragm is driven by the varying high voltages applied across it and the electrode.
2. A unit based primarily upon the force exerted between two electric charges.
3. An electric unit based primarily on the dynamic interaction of electric charges.
It is defined as a charge which, if concentrated on a small sphere, would repel with a force of one dyne which is a similar charge of one centimeter away in a vacuum.
